On my asterisk server, when i do a sip reload, i get the message "Using SIP CoS mark 4", followed by a registration time out.
I need to make that statement say "Using SIP CoS mark 5". How do I change the SIP CoS mark 4 to SIP CoS mark 5?

In
sip.conf
, there are four parameters that control theTOS
settings:tos_sip
,tos_audio
,tos_video
andtos_text
.tos_sip
controls whatTOS
SIP
call signaling packets are set to.tos_audio
,tos_video
andtos_text
control whatTOS
values are used forRTP
audio, video, and text packets, respectively.There are four parameters to control
802.1p
CoS
:cos_sip
,cos_audio
,cos_video
andcos_text
. The behavior of these parameters is the same as for theSIP
TOS
settings described above.By default, the CoS is already set to 5 for audio traffic. Signalling is set to 3. In all honesty, those values are pretty standard. Its unusual to change them in the majority of environments. I'm really not sure why you would see CoS mark 4. There is nothing using that by default.
